With four models supplying from 84,800-214,800 Btuh, and cascades of up to 16 units for even higher outputs, the Buderus GB142 modulating gas condensing boiler can provide sufficient heating comfort for any type and size of home or small to medium business, said the company. The boiler’s modulating operation — with output modulations between 30-100 percent — is matched to actual heat demand to save energy. It has an AFUE rating of 95 percent. The unit has advanced and easy-to-control integrated energy management system (EMS) controls for outdoor reset and control of an optional indirect domestic hot-water tank. The boiler comes with a prefabricated, low-loss header manifold to ensure proper flow rate through the boiler. GB142 models are approved for polyvinyl chloride (PVC) horizontal and vertical venting.
